All of the cell extensions-microvilli,cilia,and flagella-have basically the same structure.They only differ in number per cell and length.

Question

Quizplus · Accepted Answer

Microvilli, cilia, and flagella differ not only in number and length but also in their structural composition and function. Microvilli are small, finger-like projections that increase the surface area for absorption, cilia are hair-like structures that can move and are involved in movement or fluid flow over a cell's surface, and flagella are longer structures that propel cells. While cilia and flagella share a similar internal structure known as the "9+2" arrangement of microtubules, microvilli do not have this structure and are instead supported by actin filaments.
